Just upgraded my master image to SP5 and it seems that the login time went way up (it takes 65 sec from the moment OK is presses to the first instance of desktop appearing)

NW 6.5 SP7 replica servers, Zen

With SP4 the time was ~ 35 sec max (means it got longer tweice)

Is the any way to debug it (apart from LAN trace), does client provide any debug log options?
